i think the only place i disagree with you is that in my mind we really have no idea about longer-term possible side effects of the vaccine. it's a totally novel, new kind of vaccine, right?

i agree the flu shot is probably coincidence, but at least until/if i get the flu w/o it, i'm going to be guided by my first-hand experience for now. if i get the flu again, i will do more research and reconsider.
